| Jun-29-06 | | notyetagm: <jhoro: <notyetagm> the attack in your game was beautiful. 26.Qh3 was better for Luis but white is still around -1.90 down 26.Qh3 Rf3 27.Qxg4 Rxd3 28.Nd4 f5 29.Nxf5 exf5 30.Qc4+ Kg7> Thanks for the analysis and the kind words about my attack. This game really shows the importance of central control. The key manoeuvre was the 4th rank rook lift ...♖a8-c8-c5-f5-f4. If White had center pawns on d4 (covering c5), e4 (covering f5), or e3 (covering f4) then it would not have been possible. Like Dr. Lasker said, it is worth a little trouble to capture your opponent's center pawns. Your opponent's lack of central control will then make it possible for you to transfer your pieces right through the center of the board like I did in this game, which would be impossible if your opponent had better control of the center. |

I wonder.. is that due to the hardware ? .. no I got it turn it on to Infinite analysis and it finds it really quick I would say about a sec...> I guess it's the same as early Rybkas; i.e. it's programmed to stop calculating when it finds a forced mate. Nothing to do with hardware. It started analisys with promising-looking candidate moves, and found a forced mate.
Realistically, it makes no sense to try and find a quicker, simpler mate. The computer is 100% certain that it's a forced mate in 11 or 12 or 50, so it's won and that's that. |

|
| Jun-30-06 | | notyetagm: <RV> Thanks. Fritz pointed that out to me when I got home. Yes, that would have been a magnificent finish. This <PINNING-DEFLECTION> theme is very similar to how the game actually ended. That is, 27 ... ♖h4! in the variation you posted is just like my 28 ... ♗e3! in the actual game continuation. The point in both cases is that if the White queen captures the pinning piece, then she is <DEFLECTED> from defending the g2-mating focal point and then ... ♕g2# is mate. |

| Jul-07-06 | | RandomVisitor: Doesn't Rybka have a new release on July 15? |
|
| Jul-08-06 | | RandomVisitor: On my chess forum I am running a correspondence game from a critical position in the Traxler variation of the two knights defense. Rybka will play both sides, with 1 move per day. |

| Jul-18-06 | | notyetagm: <Here is the best bullet game that I have ever played!> I would be proud of this game in an OTB tourney. Of course I got a lot of help from my opponent, who played like many bullet players, completely planless, just shuffling his wood around quickly to try to win the game on time. Bullet chess is 1 minute per side for the whole game, no incremement. So the entire game last no more than 2 minutes. <What does Rybka think of my advantage after 20 ... ♘d3?>

click for larger viewI did not see this mating idea during the bullet(!) game. I played 24 ... ♕c7-c6 because I was not sure how to procede with my advanced d2-passed pawn, my queen wasn't doing anything useful on c7, and I saw that this queen move would put considerable pressure on the White kingside. |

| Jul-20-06 | | notyetagm: <RYBKA EVAL> In the following position
with White to play
click for larger viewfrom J S Morrison vs Capablanca, 1922, Maroczy notes that both players overlooked 28 ♖xf5!, which works tactically because the Black e6-pawn is <PINNED> to the Black f7-queen (28 ... exf5?? 29 ♗x♕) and 28 ... ♕xf5?? loses the queen to the <PIN> 29 ♗d3. Maroczy's exact comment is "White here overlooked that he could have gained a pawn by Rxf5 with probably a winning position." <Does Rybka think that the position resulting from 28 ♖xf5! is winning for White?>
